Answer:

\frac{10}{9}

Step-by-step explanation:

1 .1 ( .1 repeating) = \frac{10}{9}

Let x=0.1

Then 10x  = 1.1111...

= 10 + 0.(1)

= 10+ x.

So, 9x=10 and lastly, x=  \frac{10}{9}

Answer:

2π

Step-by-step explanation:

Area = πr^2

        = π2^2

        = 4π

4π is the area of the whole circle, so divide it in half to get the semicircle.

Danielle earns a 7.75% commission on everything she sales at the electronic store where she works. She also earns a base salary
Andrew [12]

The first thing thing you must do is create an equation for this problem. Remembering that 7.75% = 0.0775

($4,100 × 0.0775 + $4,100 ) + $600

Now, all you have to do is solve it. You will first have to start with the numbers in the parenthesis using the order of operation (PEMDAS).

P = Parenthesis

E = Exponent

M = Multiplication

D = Division

A = Addition

S = Subrtaction

$4,100 × 0.0775 + $4,100 ) + $600

$4,417. 75 + $4,100 + $600

$4,417. 75 + $600 = $5,017.75

Danielle made $5,017. 17 last week.

I hope this helps! :)

The bricks are built to form a garden. The perimeter of the outer square is 264 centimeters. The area of the inner square is 900
zhenek [66]

Answer:

Length: 124.7875 cm

Width: 7.2125 cm

Step-by-step explanation:

The perimeter of this area can be calculated as:

P = 2L + 2W

Where P is the perimeter, L is the length and W is the width

If the perimeter is 264 centimeters, we have that:

2L + 2W = 264

L + W = 132

The area can be calculated as:

A = L*W

Where A is the area.

If the area is 900 cm2, we have that:

L*W = 900

From the first equation, we have that L = 132 - W

Using this value in the area equation, we have:

(132-W)*W = 900

132W - W2 = 900

W2 - 132W + 900 = 0

delta = b2 - 4ac = 17424 - 3600 = 13824

sqrt(delta) = 117.575

W1 = (132 + 117.575) / 2 = 124.7875 cm

W2 = (132 - 117.575) / 2 = 7.2125 cm

Using the smaller value for W, the length will be:

L + 7.2125 = 132

L = 124.7875 cm
